Take a look at the AJAX documentation, there are plenty of examples on this site and across the Googles to trigger a server event without refreshing the page. In this case, WP is listening to an AJAX call that looks like http://example.com/wp-admin/admin-ajax.php?action=wpse20160318_batch_update. When triggered, it’ll run through your batch process an output a JSON message … Read more
Create a another filter to remove post title and post content remove search terms try this if this helpful for you add_filter( ‘posts_search’, ‘custom_post_search_author_do’, 10, 2 ); function custom_post_search_author_do($search, $query ){ if( ! empty($search) && $query->is_main_query() && !is_admin() && isset($_GET[‘search-type’]) && $_GET[‘search-type’] == ‘autor’ ) $search=””; return $search; }
I couldn’t find any WP specific event to hook in to. What you can do is set up an observer with a callback to respond to DOM changes using MutationObserver and check if the your featured image has been added in the callback. There’s no support in IE < 11 though, which may be a … Read more
$base_array = array( ‘posts_per_page’ => -1, ‘fields’ => ‘ids’, ‘post_type’ => ‘cpt’, ‘post_status’ => array(‘publish’), ‘date_query’ => array( ‘before’ => ‘next Saturday’, ‘after’ => ‘last Monday’ ), ‘tax_query’ => array( ‘taxonomy’ => ‘pas_here_taxonomy’ ‘field’ => ‘slug’, ‘terms’ => array( ‘hardware’, ‘software’), ‘operator’ => ‘IN’ ) ); $base = get_posts($base_array); echo count($base);
Enter WP_Post and the “magic” getter – did you know… $value = get_post_meta( $post->ID, ‘custom_field’, true ); …is the same as $value = $post->custom_field; So you can shorten your code to: update_post_meta( $post->ID, ‘custom_field’, $post->custom_field + 1 ); Note you cannot do $post->custom_field++ – since the property doesn’t actually exist, it can’t be modified.

Answer by @Gareth Gillman definitely works but its an expensive query if we have hundreds of posts. The function below is less expensive and using the wp native function get_post_custom_keys() if ( ! function_exists( ‘us_get_meta_keys_for_post_type’ ) ) : function us_get_meta_keys_for_post_type( $post_type, $sample_size = 5 ) { $meta_keys = array(); $posts = get_posts( array( ‘post_type’ => … Read more
I assume you are trying to add metadata to the header, such as Open Graph. To do so, you can hook into wp_head and output your content there directly. Add this piece of code to your theme’s (or your child theme’s) functions.php file: //Hook to wp_head add_action(‘wp_head’,’add_my_metadata’); function add_my_metadata(){ // Echo any content your wish … Read more
Post’s metadata can not and should not be used for validation. They can be easily manipulated. Post metadata simply stores “editable” strings or arrays, nothing more than that. The code you have copied is trying to fetch a metadata and check if its value is mp3. You can change a value of exe to mp3, … Read more
I rewrote the function from the link in your question to SQL. Keep in mind that this script will also clear the page-templates assigned to the pages. Make a backup of the wp_postmeta table first. DELETE pm FROM wp_postmeta pm LEFT JOIN wp_posts p ON pm.post_id = p.id WHERE (p.post_type IN (‘post’, ‘page’) AND pm.meta_key … Read more
One way would be to use get_posts function: $posts_with_meta = get_posts( array( ‘posts_per_page’ => 1, // we only want to check if any exists, so don’t need to get all of them ‘meta_key’ => ‘_sku’, ‘meta_value’ => ‘1’, ‘fields’ => ‘ids’, // we don’t need it’s content, etc. ) ); if ( count( $posts_with_meta ) … Read more
